Newbie's First Questions RCA TS 721 Restoration

[Chris K]

So here is why my CRT isn't working. The CRT voltages are correct except for the cathode that's supposed to be 220V DC and I'm getting -65V. I've got 220v going into terminal 1 of the brightness control and -65v coming out of the second terminal. Terminal 3 has -78v. The corresponding wires on 1, 2 and 3 are red, yellow and orange. The yellow goes out to a terminal strip where it meets the yellow wire to the CRT cathode. Orange goes to a close terminal strip where it meets R133 and a wire back to the capacitor negative of C131. ARUGHHHHHHH!
